Hey everyone,
I’m exploring different perforation patterns on a 3D mesh model.
My goal is only to change the surface pattern, not to alter the geometry.
I tried converting the mesh to a surface using several methods, but due to the model’s shape and curvature, the results are inaccurate and make it difficult to use pattern tools such as LunchBox.
I’m looking for an efficient, reliable workflow for applying patterns directly on a mesh.
A few questions:
Is there a recommended Grasshopper workflow for pattern generation directly on mesh topology (without converting to a bad surface)?
Is there a Grasshopper equivalent to UV unwrapping workflows (like in Blender) that would allow clean 2D pattern mapping on a mesh?
If not, is a hybrid workflow (e.g., Blender UV → Grasshopper patterning → back to Rhino) commonly used?
Any tips, components, or plugins would be greatly appreciated. Thanks!
Hey, thanks for sharing,
I’m not interested in re-creating the shell or flexing it between models right now.
Just experimenting with different patterns as freely as possible.
I would appreciate help and sharing on this issue.

Rhino plugins that do not ship with Rhino

I dragged the plugin and it is installed but I still can’t open the file properly.
Do you know why?
And before I dive into these installation problems I would like to understand in a descriptive way how this component will help me with the action I want to perform?
Thanks
It seems you installed the MeshCageMorph2 component. It works slightly different than the MeshCageMorph component.
The component allows morphing a mesh from one mesh to another. The reference and target mesh must be topologically identical. The idea is that you can have a simple / standard mesh which is easier to edit that a mesh in its properly aligned position on a patients arm.
This is the component you sent, I’ll check on another one.
Ok so from what I understand in a case like mine where I just want to explore different patterns this component is not effective. For the sake of clarification it is a hand orthosis but at a different stage in its design. I’m after the fitting stages
I am looking for a way to generate a UV map for this mesh that will allow me to work with patterns or knits to turn this mesh into an untrimmed surface so that I can use additional tools.
Are there any effective solutions for this?
You can use the Rhino command Squish to unroll the mesh but it’s unlikely that you can turn the mesh into an untrimmed surface. That would be a surface with 4 edges. I see more than 4 edges but maybe I’m ignoring something?
Ok, Squish is progress,
After this operation is it possible to return the layout to its previous state? And is it possible to link them together in Grasshopper?
